Mama June's 17-year-old daughter, Pumpkin, gives birth -- and tweets a photo 45 minutes later

What's the first thing one should do after giving birth? Tweet, of course.

Mama June Shannon's 17-year-old daughter couldn't wait to share the news after birthing her first daughter on Friday, December 8.

Lauryn Mychelle "Pumpkin" Shannon gave birth at 5:01 AM Friday to Ella Grace -- and by 5:48 AM, she was ready to tell the world, posting a photo of her newborn.

The teenager is apparently engaged to Josh Elfird, the father of her child: In her Twitter bio, an engagement ring emoji accompanies his name, and she's recently retweeted several photos of wedding gowns she likes.

Earlier this year, she was eager to share news of her pregnancy online, posting a collage of photos, including a sonogram, to Facebook.

It's been a year of happier news after many troubling headlines about the reality show family. Mama June famously lost hundreds of pounds via weight loss surgery, and she and daughter Honey Boo Boo are preparing for season two of "From Not to Hot" to premiere.

The more positive developments follow years of disturbing family news, including police reports alleging that Mama June's former boyfriend, Mark McDaniel molested at least one of her daughters. She also crashed the wedding of her ex-husband, Mike "Sugar Bear" Thompson, Honey Boo Boo's father, when he got married in February.
